> I agree, I wonder if C++/Java would have gone down the exception path if they had multiple return values? Its it seems to me exceptions are really a special kind of return value that doesn't clobber your single return value.
Because of constructors, I don't think they would have eschewed exceptions. Constructors don't return any value (in both C++ and Java ABI terms, they are implemented as void functions!) anyways, so having the "I don't know how to do what your arguments told me to do" be indicated via an exception being thrown is an intentional model rather then using return codes.
